Specifications
Diffuse-Field Frequency Response
stereo sampling for keyboards
stereo sound effects
Type: Stereo condenser.
Element: Electret condenser Pressure Zone Micro-
pohone.
Frequency response (typical): 20 Hz to 18,000 Hz in
a reverberant field. See Fig. 1.
Polar pattern (each channel): Omnidirectional at low
frequencies, unidirectional at high frequencies. See
Fig. 2.
recording studios and live sound
Compared to its predecessor the SASS-P, the
SASS-P MK II provides a warmer, smoother
sound with more high-frequency brilliance
(“air”) and less midrange “hardness.”

Impedance: 150 ohms rated (240 ohms actual), bal-
anced. Recommended minimum load impedance
1000 ohms.
Open-circuit sensitivity: 6.0 mV/Pa* (–44.5 dB re
1 volt/Pa*).

Polar Response
The carefully controlled polar patterns and
human-head-sized spacing between capsules
create extremely well-focused, natural stereo
imaging with no “hole in the middle.” Overall,
the reproduction of the sound field is precise
and realistic.
Equivalent noise level: 20.5 dB SPL typical
(0 dB=.0002 dyne/cm2), A-weighted.
S/N ratio: 73.5 dB at 94 dB SPL.
Maximum SPL: 150 dB SPL at the diaphragm pro-
duces 3% THD.
The SASS can accurately convey the ambient
environment for location recording film-wide
sound, or synched audio ambience (movement
of traffic) where movement heard must precise-
ly match movements in the screen image.
Polarity: Positive pressure on the diaphragm pro-
duces a positive voltage on pin 2 with respect to
pin 3 of the output connector.
Operating voltage: Standard phantom power, 12 to
48 volts DC, positive voltage on pins 2 and 3 with
respect to pin 1 of the output connector. Or two 9
V alkaline batteries (Mallory Duracell MN1604 or
equivalent).
Current drain: 1.1 mA per channel.
Material: Molded high-impact plastic.
Finish: Satin black and charcoal grey.
A foam barrier/baffle between the capsules
shapes the pickup angle of each capsule in the
front, and limits overlap of the two sides at
higher frequencies. Although the mic capsules
are spaced a few centimeters apart, there is
little phase cancellation when both channels are
combined to mono because of the shadowing
effect of the baffle.
Cable: None supplied; use 2-conductor shielded mic
cables.
Connectors: 3-pin professional audio connector (one
The SASS can be powered in the field by two
9V batteries, as well as 12-48V phantom power.
Separate left and right outputs are low-imped-
ance balanced.

Switch: Phantom/flat, phantom/low-cut, battery/flat,
battery/low-cut. Battery off in phantom positions.
Net weight: 17 ounces (482 grams).
